Implementation: (A)
Place your arms over a preacher bench. Take a barbell and hold it with an
overhand grip, place your hands shoulder width apart. Allow the bar to hang so
that your arms are fully extended. (B) Curl the barbell upward, starting the exercise
by first curling your wrist upward, then bringing the barbell up as far as
possible toward your chin. Your position on the bench should be such that, at
the top of the movement, your forearms have not come up completely to a
perpendicular angle. At the top of the exercise, lower the weight slowly back
down to the beginning of the movement.
